A third party, usually an insurance or bonding company, that guarantees a subcontractor will fulfil their contractual obligations. If the subcontractor defaults, the surety compensates the project owner. Many upstream and construction clients require surety bonds before awarding work.

A U.S. Department of Defence framework requiring contractors to meet specific cybersecurity standards before bidding on federal contracts.
